quote:Originally posted by MayoFlyFarmerYes but regardless of the geometrical shape of the universe (or anything for that matter, there must be (at least to my minds bounds) be something beyond it. The earth is shperical, yet we can escape it. We just have to travel perpendicular to its plane.When 900 years you reach look as good you will not, hmm??
quote:Originally posted by tweenerThere is other evidence that the universe is not infinite. If there were an infinite number of stars distributed throughout an infinite sized universe, the whole night sky should be as bright as the sun. This is because any direction you looked would be looking at the surface of a star, and the light would have had an infinite amount of time to reach your eye. Because the sky is dark, we know that this "infinite" and "static" universe cannot exist.----John - The Eternal Pessimist.

quote:Originally posted by SupercryptidHere are some things to consider:*If the Big Bang happened, then the universe could not possibly be infinite in expanse, unless it expanded at infinite speed from the time of the Big Bang. From our observations, the universe is expanding at a FINITE speed. Therefore, the universe MUST be finite if the Big Bang ever happened.*If the Big Bang DIDN'T happen, then it COULD be infinite. However, it could also be finite.*The universe could not have always existed. If the universe were infinitely old, then everything in the universe would be at maximum entropy right now. Yet, entropy is NOT at a maximum yet, so the universe has a finite age.
